          Abstract

          PURPOSE: Synodontia or fusion is a developmental anomaly of shape of tooth formed by union of two independently developing primary or secondary teeth. Prevalence of tooth fusion is estimated at 0.5-2.5% in the primary dentition and less in permanent dentition. The bilateral type of fusion in the primary dentition is rare and is about 0.02%. This paper describes a rare case of bilateral fusion of primary mandibular lateral and canine teeth. CASE DESCRIPTION: An 8 year old girl had a complaint of unusually large sized teeth in her mandible. After physical examination and use of periapical radiographs and study models bilateral fused teeth in the mandibular lateral incisor and canine region was diagnosed. CONCLUSION: The bilateral fusion of primary mandibular lateral and canine teeth is a rare condition and should be carefully evaluated to diagnose any associated pathology.

          OBJETIVO: Sinodontia ou fusão é uma anomalia de desenvolvimento da forma do dente formado pela união de dois dentes decíduos ou permanentes em desenvolvimento de forma independente. A prevalência de fusão dental é estimada em 0,5 a 2,5% na dentadura decídua e menor na permanente. O tipo de fusão bilateral na dentadura decídua é rara e aproximadamente de 0,02%. Este artigo descreve um caso raro de fusão bilateral de dentes decíduos incisivos laterais e caninos inferiores. DESCRIÇÃO DO CASO: Uma menina de 8 anos de idade tinha uma queixa clínica de dentes de tamanho grande anormal em sua mandíbula. Após exame físico e uso de radiografias periapicais e modelo de estudo, a fusão bilateral de dentes decíduos incisivos laterais e caninos inferiores foi diagnosticada. CONCLUSÃO: A fusão bilateral de dentes decíduos incisivos laterais e caninos na mandíbula é uma condição rara e deve ser cuidadosamente avaliada para diagnosticar quaisquer patologias associadas.

            Hemisection and vital treatment of a fused tooth--literature review and case report.

            Fusion and gemination of permanent teeth are developmental anomalies of the dental hard tissues which may require endodontic and surgical treatment for functional, orthodontic or aesthetic reasons. Following a review of the dental literature on tooth fusion and gemination, a case of fusion of a maxillary central incisor and a supernumerary tooth and its endodontic and surgical treatment is presented.
